Japan megabanks complete joint yen stablecoin test
MUFG, Mizuho, and Sumitomo Mitsui Banking Corporation (SMBC) have finalized their inaugural joint experiment involving a yen-pegged stablecoin designed for international transactions. The banks announced the completion of this trial on October 16, 2026, marking a significant milestone for the Japanese financial sector. This initiative demonstrated the viability of a unified digital currency issued by multiple major lenders, moving toward a collaborative, regulated framework for blockchain integration.
FSA Supervised Project
The pilot program took place between July 17 and July 23, 2026, functioning as a closed project under the direct oversight of Japan’s Financial Services Agency (FSA). This specific endeavor was initially chosen for development in November 2025 as part of the regulator’s Payment Innovation Project and FinTech PoC Hub. Both MUFG and SMBC issued confirmations of the results, noting that the stablecoin is legally categorized as a specified trust beneficiary right. This classification falls under the Japanese Payment Services Act, with the digital assets being fully backed by traditional bank deposits.
In this arrangement, the three participating megabanks functioned as joint settlors who commissioned the issuance of the currency. Mitsubishi UFJ Trust and Banking Corporation served as the trustee for the project, while TISI Inc. provided the necessary technological support. The primary test case involved executing cross-border settlements between the domestic headquarters of Mitsubishi Corporation and its various international branch offices.
Cross Border Settlement Test
Throughout the trial, the participants verified the entire lifecycle of the stablecoin, including its initial issuance, transfer between parties, and final redemption back into fiat currency. The banks also evaluated how multiple financial institutions can effectively coordinate on a joint issuance. This included rigorous testing of compliance protocols, specifically focusing on anti-money laundering measures and counter-terrorist financing regulations. While the pilot did not have a predetermined limit on circulation, participation was strictly restricted to KYC-verified customers of the three banks.
Commercial Deployment Targets
The consortium stated that no live transactions have been executed at this stage. The upcoming phase of development will focus on establishing governance structures, ensuring regulatory compliance, and strengthening cybersecurity and system stability. The current timeline aims for the commencement of real-world transactions within the 2026 Japanese fiscal year, which runs from April 2026 to March 2027.
For foreign exchange traders, a deposit-backed yen stablecoin represents a major structural shift. Unlike market-driven dollar stablecoins, this version operates within a bank-led regulatory environment. If the Payment Services Act trust structure holds at a commercial scale, it could serve as a template for other Japanese issuers and a regulated settlement rail for corporate flows.
Blockchain and Tradewaltz
The groundwork for this collaboration was laid in June 2026, when the three megabanks publicized a basic agreement and formed a joint council for governance. This project is part of a broader interest in blockchain among Japan’s top lenders. MUFG, Mizuho, and SMBC are also engaged in related work through TradeWaltz, which covers asset trading, ownership transfers, and trade settlement.
